I forgot to address this comment, so here's the test:

$ cat test.c
void main()
    printf("atoi()=%d\n", atoi(""));
$ ./test

So I think it works as expected. Of course, now that I think about it,
it's kind of stupid to use atoi() in the first place, I could just do
*p == '1'. If anyone cares I can change it, although it's clearly not
in a performance-critical part of the code.

I'll apply soon, but I sort of forgot and didn't really have time
either (family visit :-) ), I'll do it as soon as I find time.
